Product details

The DSC1123AI2-148.3520T is a MEMS-based XO (Standard) oscillator delivering a 148.352 MHz LVDS output from a 2.25V to 3.63V supply rail.

±25 ppm frequency stability holds the output within 3.7 kHz of 148.352 MHz across the full temperature and voltage range. For a 1 Gbps LVDS serial link, that jitter budget leaves room for the receiver PLL to track without bit errors. This lets the system clock gate the oscillator without an external load switch.

6-SMD, No Lead Exposed Pad package measuring 7.00 mm x 5.00 mm with a seated height of 0.90 mm.

Frequently asked questions

Is the DSC1123AI2-148.3520T AEC-Q100 qualified?

Yes, it carries AEC-Q100 qualification. That means it passed the automotive-grade reliability stress tests: temperature cycling, ESD, latch-up, and early-life failure rate per the AEC-Q100 rev-H specification.

What is the output type and frequency of the DSC1123AI2-148.3520T?

LVDS output at 148.352 MHz. The LVDS differential pair delivers a low-swing, low-noise clock suitable for high-speed serial interfaces like Gigabit Ethernet, PCIe, or SATA reference clocks.
